Why is it not necessary to dertemine accurately the cell constant of the conductance cell before carrying ou the experiment?
Although determining the cell constant accurately is ideal for precise measurements, it is not always necessary before conducting the experiment. As long as the conductance cell is properly calibrated, any variations in the cell constant can be accounted for in the calculations. The key is consistency in the calibration process to ensure reliable and reproducible results.

Why is it necessary to determine accurately the cell constant of the conductance cell before carrying out this experiment?
Determining the cell constant is crucial because it relates the conductance of a solution to the actual concentration of ions present. Without an accurate cell constant, the conductance measurements may not reflect the true concentration of ions in the solution. This could lead to incorrect conclusions and data in the experiment.
How does the concentration of electrolytes affect the conductivity of a solute?
The conductance of a given conductor, C = La/l ..(i)\ L = l/Ra ..(ii)The resistance is expressed in units of ohm, the conductance has units of ohm-1 or mho.The conductance of solutions is also governed by the same relations. From (i), if l = 1,a = 1, the specific conductance L = C. That is,the specific conductance (L) is the conductance of the solution enclosed between two electrodes of 1 sq. cm area and 1 cm apart. when you dilute the solution the concentration decrease and the specific conductance also decreaseThe conductance of a solution depends upon the number of ions present and hence on the concentration. To compare the conductivity of different solutions, it is necessary to take the concentration of the solutions into consideration. It is done by using equivalentconductance, l.
Why is it necessary to weigh the iron fillings accurately though the mass of copper sulfate taken was only approximate?
This is necessary in analytical chemistry, to obtain correct results.
Why is it necessary to use laboratory apparatuses in conducting an experiment?
Some experiments aren't possible without proper equipment. It is safer to use and accurate values can be calculated in laboratory activity. It is best to use aseptic techniques, so not to contaminate, by lighting a fire.
Kat was getting ready to study gas in the laboratory Before beginning her experiment she remembered to measure the total volume of the flask that would contain the gas what else should she measure?
Kat should also measure the temperature and pressure of the gas inside the flask before beginning her experiment. These measurements are necessary to accurately calculate the properties of the gas, such as its volume, using the ideal gas law equation.

What are necessary precautions for safety purposes while conducting an experiment?
The necessary safety precautions when conducting an experiment depend on what is done during the experiment and where it is done.
Why is an experiment necessary?
An experiment gives us proof that we are right.

Why was it necessary to degas the sodas prior to the experiment?
It was necessary to degas the sodas prior to the experiment to remove any dissolved gases, such as carbon dioxide, in order to prevent interference with the results of the experiment. Presence of dissolved gases can affect the accuracy of the measurements taken during the experiment.
The analysis of a data gathered during a particular experiment is necessary in order to?
Draw a valid conclusion for that experiment.
Why is control setup necessary in an experiment?
Without controlled setup in an experiment. How can the researcher know his data is comparable for study?
Is it necessary for a signature to be legible?
Yes, it is necessary for a signature to be legible in order to accurately identify the person who signed the document.
What is the procedure for doing the experiment?
To conduct the experiment, first, gather all necessary materials and equipment based on the experimental design. Next, follow the step-by-step protocol, ensuring to measure and record data accurately at each stage. After completing the procedures, analyze the results and compare them to your hypothesis. Finally, document your findings and any observations for further evaluation.
Why is a skilled labor necessary for a business?
it is necessary because, it is use to show that the business will function accurately with highly educated persons
How do you write an experimental procedure effectively?
To write an effective experimental procedure, clearly outline the steps in a logical order, include all necessary materials and equipment, provide specific measurements and variables, and ensure the procedure is detailed enough for someone else to replicate the experiment accurately.
